HAIR CLIIPERS AND THE LIKE.

Application filed September 25, 1826. Serial No. 58,583.

This invention relates to new and useful improvements in hair clip ers and the like,

and the primary object tiereof is to pro{ l6 tained true so that the cutters contact as near perfect as possible. After bulfing, the studs are positioned and must be turned to aline, same with the guide slots of the upper cutter. It now in turning the studs,

80 the heads oi the latter disfigure or cause irregularities in the surface of the lower plate or cutter, a true contact with the upper plate or cutter will not be had.

This invention, briefly proposes an iso- I lated contact area for enga ement with the stud whereby regardless o? the extent of adjustment of the latter, the contact surface of the plate will be unaffected and its trueness preserved.

In the drawings Fig. 1 is a fra mentary lan view of the invention applie to hair ippers;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fi 3 is a to plan view of the lower cut- 86 ter p ate with t e stud thereon; and i Fig. 4 is a view similar to Fig. 3, but with the stud removed.

In accordance with the art, illustrated in connection with hair clippers, 1 designates the bottom cutter plate, 2 the top outter plate, the latter provided with slots 3 I for receiving the usual guide studs 4.

The guide studs 4 are threaded into engagement with the bottom or lower cutter plate so that same are removable to enable buifing or polishing of the contact or upper face of the bottom plate. The above mentioned parts are of common construction. well known in the art.

The present invention resides in the formation of an annular groove 5 in spaced relation to the threaded hole 6 for reception of the threaded end of the guide stud 4 so as to provide a circular seat- 7 isolated .from-the remainder of the contact surface of the bottom plate. The roove 5 is of a width 50' as to enable t e base of the head of the stud to overhang the groove and thus be prevented from engaging the contact surface of the plate. Y

From the foregoing it will be seen that the invention provides an isolated area, remote from the contact surface of the plate, and within which area the base of the stud head is confined, so that regardless of the degree or extent to which the stud is forcibly turned against the late, the contact surface of the latter wil not be affected. 1f the seat 7 is mashed or compressed by turnin of the stud the metal will flow lateral y into the groove. The art of the plate surrounding the hole 6 is a so slightly cut away at 9 so as to rovide for any lateral flow of the metal ofseat 7.

While the invention is disclosed in connection with hair clip rs, still it is to be expressly underst that the same is equally applicable to other instances, where similar conditions exist. Consequently the present disclosure merely instances one exam le, or use of the invention.

aving thus described my invention what I claim as new and desire to secure by Letters Patent is:-

1. A member having a finished surface adjustable in said aperture and a seat compressible for the head of said stud isolated from the finished surface of the member so as to prevent contact of the stud head with such surface.

2. A member having a finished surface and an adjustable element provided with a contact face thereon and a compressible seat for said faceof the element isolated from the finished surface of the member to prevent en agement of the contact face with the finis lied surface.

3. A member having a finished surface and a threaded aperture with a guide stud adjustable therein said memberhaving a circular groove spaced from and. surrounding the aperture to form a compressible seat for the head of the stud isolated from said finished surface so as to prevent contact of the stud head with such surface.

4. A member having a finished surface and a threaded aperture with a guide stud adjustable therein, said member having a circular groove spaced from and surrounding the aperture to form a seat for the head of the stud isolated from said finished surface so as to prevent contact of the stud head with such surface, the member .being further formed with a circular groove extending into said aperture.

5. A member having a finished surface and a threaded aperture with a guide stud adjustable in said aperture and having a pair of spaced circular grooves forming a circularseat for the head of the stud which
